How to make Prawns Boil With Spicy Horseradish Sauce

Squeeze lemon juice into 4 qt water in a 6- to 8-quart pot, then stir in lemon quarters, Creole seasoning, 2 teaspoons cayenne, bay leaves, garlic, potatoes, and 2 tablespoons salt (omit salt if it is the first ingredient in seasoning).

Bring to a boil, then simmer, partially covered, until potatoes are almost tender, 10 to 12 minutes.

Increase heat to high, then add corn and simmer, partially covered, 4 minutes. Stir in prawns and cook until just cooked through, 2 to 3 minutes.

Meanwhile, stir together ketchup, mayonnaise, horseradish, and remaining 1/2 teaspoons cayenne.

Drain prawns, potatoes, and corn and serve with sauce.
